#DOWNLOAD IDEFRAG FOR MAC FREE INSTALL#

If you don't already have a _bootable_ backup volume, I'd STRONGLY suggest that you consider creating one. You have to boot from _another_ volume that has iDefrag on it, and then 'aim' iDefrag at your 'target volume', and let iDefrag do its thing. It's like asking a brain surgeon to do surgery on himself.

You can't do a 'full defrag' on a volume that you're booted up from. 'It asks me to restart from a DVD or something, how do I do it? I want to defrag the whole drive, it is really slow.' It should seem that putting all related files together would make stuff quite a lot faster, but it doesn't, just a little bit, plus some placebo effect.

What can go wrong here?Īnd as a final note: I'm not totally sure of the long term benefits of iDefrag. Sort by size, and what do you get? Thousands of files copy -> check the copy -> delete original. When you let iDefrag examine your drive, and click on the 3rd tab (can't remember what its called) it gives you a big list of files that are fragmented. HFS+ does not defrag every file below 20MB (if you read the apple KB linked above) it says that defragging every one of the hundreds of thousands of files would be a useless exercise. Boot into that drive, and run iDefrag from it. There is no need to update that copy of OS X.

Clone your drive to that new one or install OS X on it from an install disk. OP: do you have any sort of external hard drive? If you have Macbook, then a USB will do it too.
